2003 Grand Am V6 motor rebuilt will not start

[pjsanders]

I had my eengine rrebuilt and now it wont start. Mechanic thinks it might be a security system sita=uation. I don't know. Any ideas?

If the security light on the dash is flashing then just do a reset. Do you have any other details?

As asked do you have the security light on?
Does the engine crank and not start or nothing happens?
Perhaps you should consider a new mechanic in the future.

It is a friends car I am helping him with. I can't say about the security light, but if it is on, can you tell me how to reset it? thanks a lot.
